To investigate the effect of different texture wavelength deterioration on pavement skid resistance, a tire-pavement tribology model was developed through theoretical derivation and numerical simulation, and five asphalt mixture specimens were used for full life-cycle performance analysis. The results show that simulation model can efficiently calculate stress contribution of each asperity on 3D texture, resulting in simulation outcomes closely matched those of the laboratory tests. Two-dimensional (2D) pavement profile and 2D-PSD show apparent consistency in initial and subsequent stages, it correlates with the asphalt film shedding and aggregate crushing during polishing. Intrinsic factors mainly determine skid resistance durability, which is closely related to the percentage of different particle size aggregates and skeletal structure of the asphalt mixture.
